APPARATUS FOR-GAUGING ASSOCIATED ELEMENTS.

Application 'led January 30, 1922. Serial No. 532,652.

To @ZZ 'whom itmay conce/m.'

Be it known that I, ERNEST O. DrnfrnRicH, a citizen of the UnitedStates, residing at Akron, in the county of Summit and State ofOhio,have invented a certain new and useful Apparatus for GaugingAssociated Elements, of which the following is a speciiication.

This invention relates to methods and apparatus for determiningfthenumber of associated elements, such as the threads in woven or otherfabric, occurring within a linear unit of measurement.

.Its general object is to provide an improved method and an improveddevice for such purposes. A more specific object is. to

provide an improved, compact and convenient device giving a directreading of the number of uniformly spaced elements occurring within agiven distance, as in counting the number of threads to the inch infabrics.

Of the accompanying drawings:

Fig. 1 is a plan View of a fabric gauge embodying and adapted to carryout a preferred form of my invention, with parts broken away.

Fig. 2 is a section on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary, transverse section of the device and a piece offabric in position thereunder.

Fig. 4 is a diagrammatic fragmentary plan view of a 'modication`Referring tothe drawings, 10 represents generally a flat, boX-likestructure comprising a rectangular frame 11 and bottom and top plates 12and 13, respectively, secured thereto. frame 11, are pivoted, at 15 and16 respeci tively, a pair of arms 17, 18, the outer ends of which areconnected by a link 19. The frame member 14, arms 17, 18, and link 19thus form a parallel-motion.

Stretched between the arms 17, 18 are parallel, spaced-apart strands 20,20, which are preferably of fine wire and may conveniently be secured tosaid arms in proper parallel, spaced relation byr being laced throughholes appropriately positioned in said arms, as shown clearly in Figs. 1and 3.

The lower and upper plates 12 and 13 are formed with registeringopenings or windows 21, 22, respectively, through which the fabric,shown at 23 (Fig. 3), may be seen from above when the device is laidthereon. The upper plate 22 is also formed with an To one side member14, 'of thev arcuate slot 24, substantially concentric with n the pivot16 of the arm 18. 25 is a hand knob Von the upper face of the device,yits stem extending downward through theslot 24 and being secured totheflink 19, for moving the latter to actuate the parallel-motion ofwhich ksaid link is a part, and thereby equally to vary the `spacingofthe wires 20. A scale 26 is provided on the upper face of the plate 22adjacent the slot 24, and 27 is an indicator therefor, secin'ed to=thehandk knob 25.'

Pins 28, 28, may be vprovided on the under face of the device forholding it in position upon the work.' The frame member14, at the end ofthe window 22, preferably is beveled oilz as shown at 29 to provide astraight-edge 30 (Fig. 1) close tothe work, f to assist the eye inyplacing the device accurately thereon. A magnifying glass 31 may besecured in position over the window 22, by Vmeans of aframe 31a, asshown, VLto facilitate the positioning of the wires r20, as hereinafterdescribed. y

In the operation of the device, in determining the number of threads tothe inch in fabric, for example, the device is placed upon the fabric,as indicated in Fig. 3, preferably with the straight edge 30 directlyover one of the spaces between the threads 23, 23, the wires 20vthenbeing parallel to the threads. The handk knob 25 is then moved in theslot 24, equally varying the spacingrofthe parallel wires 20 until eachof said wires registers with one of the spaces between the threads 23a.The number of threads to the inch may then be read directly from theposition of the indicator 27 upon the scale 26. Equally accurate resultsmay be obtained byv placing the straight edge 30 and wires 2O directlyover the threads 23a, 23, but in practice I find it easier to registerthe wires with the intervening spaces.

The wires 2O may be brought into registry with successive threads orspaces, or with alternate threads or spaces, as shown in Fig. 3, or theymay be matched with every third or fourth thread, for example. yThe.scale 2G may be calibrated to correspond with either of these severalmodes of procedure, and the correct result for the other modes ofprocedure may be arrived at by multiplying` or dividing the reading ofthe indicator 27 by the proper small integer. The device thus, as wellas by reason of its C?? LAM considerable range of adjust-nient, may beelectively used Yfor gauging fabrics or other articles having eitherWidely or closely spaced elements.

In the modification shoivn in F ig. 4, the strands here designated 20a,20a, are stretched in parallel relation between helical springs 32, 32,said springs being 'fastened at one end to the frame of the device (nothere shown) and at the other to the head 'E a T-shaped member 33 havingits stem slidably mounted in brackets 34. 34. The rear end ot said stemis slotted at to receive the axle 36 of an eccentric cam 37, the latterbeing adapted to coact with an off-set lug 38 on the end of said stem tosecure said T-shaped member 33 in adjusted positions, againstthe actionof the springs 32. IVith this modified form of device the spacing of thestrands may be equally varied and the strands held in adjusted positionsWhile their parallel relation is preserved.

` Other modilications may be resorted to without departing from thescope of my invention, and I do not Wholly limit my claims to thespecific embodimentshown.

I claim: Y

l. A device for determining the number of associated elements occurringWithin a linear unit, said device comprising a set of equally spaced,parallel strands, means for moving said strands apart While maintainingtheir equally spaced and parallel relation, and an indicating mechanism,reading directly in terms of the numbers of strands per linear unit intheir successive adjusted positions, associated with said moving means.

2. A thread counter for fabric comprising a set of elements equallyspaced apart, means for so moving said elements as equally to vary theirspacing, a mounting for said elements and said moving means, a scaleassociated with said mounting and said moving means, said scaleregistering the number of elements occurring Within a.

linear' unit at different settings, and a magnifying glass disposed insuch position as to magnify objects adjacent .said elements.

3. A device for determining the number of associated elements occurringWithin a linear unit, said device comprising a parallel motionmechanism, a set of equally spaced strands stretched between oppositearms of said mechanism, a cale, and an indicator therefor mounted on a.movable arm oi said niechanism, said scale being so calibrated and sodisposed with respect to the indicator as to show by direct readings thenumber of strands occurring in a linear unit as the parallel motionmechanism iS moved into varying positions.

In witness whereof I have hereunto set my hand this 28 day of January,1922.
